The invention relates to a combined annular mist flow phase-splitting flow measuring method. The combined annular mist flow phase-splitting flow measuring method comprises the following steps: measuring an average liquid membrane thickness of an annular mist flow in real time by using two pairs of electric conductive annular wall-attached sensors; performing relevant analysis on signals measured by the two pairs of front and back annular electric conductive sensors according to a relevant speed measuring method to obtain an average liquid membrane interface flow rate, and solving a mass flow of a liquid membrane according to the average liquid membrane thickness and the liquid membrane interface flow rate; acquiring gaseous phase density by using a vortex sensor; obtaining a read gaseous phase flow through calculation; and using the measured liquid membrane flow, the read gaseous phase flow rate and the read gaseous phase flow as known quantities, performing the iterative solution on an entrainment rate E and
